Etymology

Origin of coop

First recorded in 1250–1300; Middle English coupe “basket,” perhaps from Scandinavian or ultimately from Latin cūpa “cask, tub” ( see cup ( def. )); cognate with Norwegian kaup “wooden can,” Old English cȳpa “basket”


Explanation

A coop is a small enclosed area or structure where chickens are kept. If you feel cooped up, you feel like you’re stuck in a small space, like a giant chicken in a tiny cage. A coop is where chickens get shelter from bad weather and predators. Without a hyphen, the word co-op, which is short for co-operative organization, turns into coop. That can be confusing to chickens because they don’t know if they will have meetings or a safe place to lay eggs. Coop comes from the Old English word cype, "basket" or "cask," with the Latin root cupa, "cask" or "tub."
